No one in the CO forum could answer with experience so I thought I would ask the question here. I usually travel with a carry-on, under the size requirement. Now in addition to that I will have a recently purchased LowePro Mini Trekker camera case. Will the airlines consider this too big to be my additional personal item? They list camera cases a being on the approved personal item list but this may not be what they are thinking. Appreciate input from anyone that has traveled with a similar case.
